Interesting. Do you know that the rotation circle of the crankshaft is biased slightly below the bores of the cylinder? I guess if the center of the rotation was directly in line with the center of the bore, then it wouldn't make any difference. That's why I ask about what you've drawn.

Thanks...

What I have drawn is a rule for all the engines (bikes, cars, trucks, etc) with piston offset.
